(680 kgs.) ofsteam per hour. By referring to the proper initial reduced pressure column “From 100psi/Up to 50psi (6.9 – 3.4 bars)”, you will find thecapacity of 1560 lbs./hr. (708 kgs./hr.) for the 1" (25mm) Model 127 valve corresponds most closely to the required capacity of 1500 lbs./hr.NOTE: For reduced pressures greater than those shown for each Initial Pressure column above, refer to the Detailed Capacity Table in theWatts brochure F-127. Be sure to determine both Initial Pressure and Reduced Pressure setting, or the range required.For assistance, contact your local authorized Watts agent or visit our website at www.wattsreg.com19
